In this blog i will guide you through the process of setting openCV on your linux machine.Open cv is open source computer vision library of programming functions which is very helpful in case you want to play with your images .

First of all what we have to do is get the things upto date

Open your terminal and write this command to update

sudo apt-get uodate && sudo apt-get upgrade

After that install the dependencies which will later help us in compiling the openCV library

Now download the current stable version of openCV. For my project i was required of openCV-2.4.5. You can directly download the below mentioned command and remmember the path where you have downloded it.

wget https://github.com/Itseez/opencv/archive/2.4.5.tar.gz

Untar the tar file

tar -xvf 2.4.5.tar.gz

Now after this we have to make a cmake file for that what we have to do is open the opensc-2.4.5 folder and create a new folder called build.
